Sleeping Pills and Memory Loss. Elderly people have more trouble sleeping than younger folks. Some causes include waking to urinate, pain due to arthritis or other inflammations and lack of exercise. Sleeping pills can help, but they have a dark side. They can cause memory loss.
Ambien and other sleep medicines like Xanax can cause temporary memory loss or amnesia.. A patient may forget what has happened during the period after taking the Ambien and before it wears off. To avoid memory problems, you should only take Ambien before a full night's sleep.mbien should only be used for short periods of time (such as 1 or 2 days) and generally for no longer than 1 or 2 weeks. Taking Ambien may cause you to feel drowsy, dizzy, lightheaded, or less alert. You should check with your doctor immediately if you feel clumsy or unsteady.
